Problems solved by technology

Two anode bars are set in each electroplating tank, and the workpiece is hung on the cathode bar between the two anode bars for electroplating. When the workpiece is electroplated in one electroplating tank and enters the next process, the cathode bar and the workpiece pass through other During the electroplating tank, the electroplating solution on the workpiece will drip down on the anode bar, which will cause corrosion to the anode bar, and the electroplating solution will be polluted and easily aged in advance
In addition, because the cathode bar in the same electroplating tank is connected in parallel between the anode bar and the cathode bar, the high-end current of the voltage is large, so the current distribution between the multiple workpieces is uneven, and the two parts of the cathode bar hang on the two sides of the cathode bar. The coating of the workpiece at the end is thicker, which makes the quality of the electroplated products obtained inconsistent

Abstract

The electroplating apparatus has one or several electroplating baths set between two tracks of traveling crane. Inside the electroplating bath, there are two parallel anode rods parallel to the tracks, one cathode rod with hung workpiece, two conducting slide rails between two anode rods, one conducting slide sleeve on the cathode rod for matching with the slide rails, one elevating mechanism for connecting the cathode rod via a hanging rope to the traveling crane. During electroplating, the cathode rod is driven with the traveling crane to move forward slowly and no corrosive electroplating solution drops from the workpiece to the anode rods. The present invention can obtain homogeneous coating thickness and stable product quality.

Description

technical field [0001] The invention belongs to the technical field of surface treatment, and in particular relates to an electroplating device. Background technique [0002] The principle of electroplating is to rectify the three-phase alternating current into low-voltage, high-current direct current through a high-power rectifier, connect the anode of the power supply to the anode bar insoluble in the electroplating solution, hang the workpiece to be plated on the cathode bar, and electroplate the ion The movement in the plating solution produces an electroplating layer on the surface of the product to be plated. At present, in various electroplating production lines, in order to improve production efficiency, several mutually independent electroplating tanks are usually arranged side by side along the traveling direction of the vehicle to simultaneously electroplate multiple workpieces. Two anode bars are set in each electroplating tank, and the workpiece is hung on the ...
